Setting up wireless connection was surprisingly easy and I was able to get it up in minutes, so points there for Apple. I connected the machine through the built-in ethernet at work and the performance was dog slow! I saw packet loss of about 70 percent so definite negative points. Initially I thought that there might have problem with the ethernet hardware but then I read online that Macbook Pros have problem if they are on a LAN that has 802.1q/vLAN. The problem is discussed here.
I hook the notebook on another network and it performed fine so it seems like I got bit by this same bug. I'm surprised that Apple still haven't fixed it, but I suspect this mainly effect corporate users which might still not be a big customer base for Apple to pay attention to.
